Now i don’t know why changing the Month from 12th to 11th gave me the correct date and time, i would be really obliged if someone can explain this simply and if possible with a small uncomplicated example.

Answer 1

Months in a Calendar are zero-based

The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0

Assuming a Gregorian calendar, 11 is December, and 12 is January of next year, precisely the way your program shows it.
